Find the zero of the polynomial in each of the following cases.
f(x) = x + 2

f(x) = x + 2

f(x) = 0

⇒ x + 2 = 0

⇒ x = 0 – 2

⇒ x = -2

∴ x = -2 is the zero of the polynomial x + 2.

Verify whether the values of x given in each case are the zeroes of the polynomial or not?

f(x) = 3x² - 1; x = -

Verify whether the values of x given in each case are the zeroes of the polynomial or not?

f (x) = 2x - 1, x =
